 Lot 45. — A collection of Hemiptera determined by Professor P. R. 

 Uhler during the year 1883. See correspondence in Letter 

 Book I and Letter File I. The subnumbers refer to a list fur- 

 nished by Professor Uhler, which is in Letter File I, pp. 166- 

 172. 

 The last extract illustrates a very important use made of lot 

 numbers. In this way it is easy to label each specimen so that its 

 name and the authority for the determination can be easily ascer- 

 tained. And as the label is a small one placed upon the pin, there is 

 no danger of the specimen and 

 its label becoming separated. 

 These labels are used in addition 

 to the larger labels placed at the 

 head of each series of specimens 

 in a systematic collection.

Blank Forms for 

 Labels. — In arranging 

 specimens in a systematic 

 order in a collection, there 

 should be placed at the 

 head of each group of in- 

 sects a label bearing the 

 name of the group. These 

 labels are used in addition 

 to those already described, 

 which are always left on 

 the pins or in the bottles 

 as the case may be. The 

 group labels are of larger size than the preceding, 

 and are usually written on blank forms like those 

 shown in Fig. 286, except that it is customary to have 

 the forms printed in red ink ; and the forms are twice 

 as lonof and twice as wide as shown here.
